>Description:
	Recent changes to libpcap routines have broken pppd's ability to
	parse active filter expressions.  NB:  pppd uses a private version
	of gencode.c but uses the libpcap version of optimize.c.  The bug
	manifests itself as an infinite loop in routine bpf_optimize().
>How-To-Repeat:
	Insert the following line in /etc/ppp/options file:

active-filter "udp or (tcp and not tcp port ntp)"
>Fix:
	Unknown at this time.
